Therefore, there is no command for recovering the corresponding error in E300, For this reason, there is no command. In addition, a corresponding command is not stored in an error that cannot be automatically recovered by the apparatus itself.

  Here, the error recovery command 61 stored in the error recovery command storage unit 123 controls electronic devices represented by a PJL (Printer Job Language) command, a PS (Post Script) command, and a PCL (Printer Control Language) command. Possible command formats.

  FIG. 5 is a diagram illustrating a configuration example of the error data 70 generated by the error analysis unit 162 when an error occurs in the printer 10 as will be described later. The error data 70 is a combination of error information 41, error code 42, error recovery procedure 51, and error recovery command 61. Here, error data 70 generated when the error code 42 is E001, E240, or E300 is shown.

  FIG. 6 is a diagram illustrating a display example of an error screen 80 and an error treatment screen 82 displayed on the display unit 152 (FIG. 1), as will be described later, when an error occurs in the printer 10. As shown in FIG. 5A, on the error screen 80, error information 41 obtained from the error data 70 and an error recovery procedure 51 are displayed, and a touch panel type recovery button 81 for instructing error recovery is displayed. Is displayed. Here, when the recovery button 81 is pressed, an error recovery command 61 is executed, and an error handling screen 82 is displayed as shown in FIG. Here, an example of an error screen 80 and an error action screen 82 displayed when the error information 41 is a paper size error is shown.

  The recovery button 81 may be a touch panel type button used in the present embodiment to recognize that the recovery button 81 is pressed by touching an image displayed on the display unit 152 (FIG. 1), or a machine. A typical recovery button 81 may be provided on the printer 10. The display unit 152 may be configured so that the user can recognize the error. For example, the display unit 152 may be configured to notify the error by blinking an LED and to specify the type of error at the blinking speed.

  An operation example of the electronic system in the present embodiment with the above configuration will be described below.

  When the printer 10 (FIG. 1) receives image data from the PC 20 by the transmission / reception unit 14, the printer 10 (FIG. 1) analyzes the image data by the data analysis unit 161 and prints it by the printing unit 18. In this process, when an error is detected, the error detection unit 17 generates an error code 42 corresponding to the type of error. The error analysis unit 162 acquires error code 42, error information 41, error recovery procedure 51, and error recovery command 61 related to the detected error, generates error data 70 (FIG. 5), and generates an error screen 80 (FIG. 5). 6 (a)) is displayed on the display unit 152. The user confirms the error information 41 and the error recovery procedure 51 on the error screen 80 and operates the recovery button 81 to instruct an error recovery. In the printer 10, when the recovery button 81 is pressed, the data analysis unit 161 analyzes and executes the error recovery command 61.

  FIG. 7 is a flowchart showing the flow of error recovery processing executed by the printer 10 when an error occurs during the printing process. With reference to FIGS. 1 to 6, the operation of the printer 10 is described based on this flowchart. Further explanation will be given.

  When the printer 10 receives image data from the PC 20 by the transmission / reception unit 14 (step S10), the image forming process, that is, analysis of the received image data by the data analysis unit 161 and printing of the analyzed image data by the printing unit 18 are performed. Is started (step S11). The error detection unit 17 monitors whether an error has occurred during the image forming process, and generates an error code 42 corresponding to the error when an error has been detected (Yes in step S12). Based on the error code 42, the error analysis unit 162 generates error data 70 (FIG. 5) including error information 41, an error recovery procedure 51, and an error recovery command 61 (step S13). On the other hand, if no error is detected during the image forming process (No in step S12), the error recovery process is terminated without being executed.

  The display unit 152 displays the error screen 41 (FIG. 6) including the error information 41 and the error recovery procedure 51 of the error data 70 generated at this time, and the recovery button 81 (step S14). The user looks at the error screen 80 to determine whether or not to recover the error. When it is determined to recover, the user presses the recovery button 81 by a touch operation to instruct error recovery. Thus, the printer 10 determines that the user performs error recovery (step S15, Yes), and the data analysis unit 161 analyzes the error recovery command 61 and executes the error recovery command (step S16).

  For example, as illustrated in the error screen 80 of FIG. 6, the error that occurred is a paper size error with an error code 42 of E240 (FIG. 5), and the user confirms the error screen 80 of FIG. When the recovery operation is executed by the recovery button 81, an error handling screen 82 shown in FIG. 6B is displayed by executing the error recovery command. The user selects and sets a normal paper size while checking on this screen, and recovers the paper size error. Although not described in detail here, for example, the printer 10 temporarily stops the image forming process when an error occurs in step S12, and resumes the image forming process when the error is recovered in step S16. It is assumed that it is set to.

  On the other hand, if the user does not execute error recovery, it is determined that the user does not perform error recovery (No in step S15), and the error recovery process is terminated without executing the error recovery command. Here, if the user does not execute a predetermined recovery operation after a predetermined time has elapsed after displaying the error screen 80, it is determined that the user does not perform error recovery.

  FIG. 8 is a flowchart showing a series of generation processes when the error data 70 is generated in step S13 of the flowchart of FIG. 7, and the processing contents will be described based on this flowchart.

  When an error is detected by the error detection unit 17 of the printer 10, the error analysis unit 162 acquires an error code 42 (FIG. 5) generated by the error detection unit 17 corresponding to the error content (step S20). Next, the error analysis unit 162 acquires error information 41 corresponding to the error code 42 from the error information table 40 (FIG. 2) (step S21), and converts the error information 42 from the error recovery procedure table 50 (FIG. 3) to the error code 42. The corresponding error recovery procedure 51 is acquired (step S22), and it is determined whether or not the error recovery command 61 corresponding to the error code 42 exists in the error recovery command table 60 (FIG. 4) (step S23).

  If the error recovery command 61 corresponding to the error code 42 exists (step S23, Yes), the error recovery command 61 corresponding to the error code 42 is acquired from the error recovery command table 60 (step S24), and the error The information 41, error recovery procedure 51, and error recovery command 61 are combined to create error data 70 (FIG. 5) (step S25).

  On the other hand, if the error recovery command 61 corresponding to the error code 42 does not exist (No in step S23), only the error information 41 and the error recovery procedure 51 are combined to create error data 70 that does not include the error recovery command 61. (Step S26).

  In this embodiment, a printer which is an image forming apparatus is described as an example of an electronic apparatus. However, in addition to the printer, for example, an operation unit for operating the apparatus, such as a scan or a modem, and a display unit for recognizing an error. The present invention can be applied to any electronic device provided with a storage unit for storing an error recovery command.

  Although not specifically described in the present embodiment, it is preferable to provide the storage unit 12 with an error recovery log storage unit that records information about recovered errors. Accordingly, for example, the control unit 11 stores the execution record of the error recovery command in the error recovery log storage unit, so that the user can later confirm the recovered error.

  As described above, according to the system of this embodiment, when a simple error other than a physical error such as a paper jam occurs in the printer, an error recovery command and a means for executing the command are provided. Therefore, it is possible to reduce the labor and time spent on the work for recovering the error, and simplify the work.

Embodiment 2. FIG.
FIG. 9 is a block diagram showing a main configuration of the electronic system according to the second embodiment based on the present invention.

  This electronic system is mainly different from the electronic system of the first embodiment shown in FIG. 1 described above in that an error processing unit 90 is provided in the PC 220 (PC 120 in the first embodiment), and between the PC 220 and the printer 10. The communication contents are different. Therefore, in the electronic system of the present embodiment shown in FIG. 9, the same reference numerals are given to the parts common to the electronic system of the first embodiment shown in FIG. , Explain different points with emphasis.

  In the electronic system of the first embodiment shown in FIG. 1, when an error occurs in the printer 10, the user who has displayed the error screen 80 (FIG. 6) on the display unit 152 of the printer 10 and confirmed the display content. In the electronic system of the present embodiment shown in FIG. 9, when an error occurs in the printer 210, an error screen is displayed on the display unit 24 of the PC 220. 80 (FIG. 6) is displayed, and an error recovery command for recovering the error is executed in the printer 210 in accordance with an instruction given by operating the PC 220 by the user who confirmed the display content.

  Therefore, the control unit 11 of the printer 210 transmits the error data 70 created by the error analysis unit 162 to the PC 220 via the transmission / reception unit 14 in the same manner as in the first embodiment, and the PC 220 as will be described later. When the error recovery command transmitted from is received by the transmission / reception unit 14, the data analysis unit 161 analyzes it in the same manner as in the first embodiment, and executes the error recovery command.

  On the other hand, the PC 220 includes an error processing unit 90 whose operation is managed by the control unit 21 when viewed by function. When the error data 70 sent from the printer 210 is received by the transmission / reception unit 25, the error processing unit 90 The error data 80 is processed, and an error screen 80 (FIG. 6) including information acquired from the error data 70 is displayed on the display unit 24 such as a monitor screen. The error recovery command 61 (included in the error data 70) for recovering the error at that time is transmitted from the transmission / reception unit 25 to the printer 10 in accordance with an instruction performed by operating the input unit 23.

  The error screen 80 may be displayed via a printer driver which is a device driver for transmitting data created by an application to the printer 210, or the data received from the printer 210 is the error data 70 on the PC 220. You may display using the application for exclusive use started in a certain case.

  FIG. 10 is a flowchart showing the flow of error recovery processing executed by the printer 210 and the PC 220 during the printing process by the printer 210, and is based on this flowchart with reference to FIGS. 2 to 6, 8, and 9. The operation of the electronic system will be further described. Note that steps S10 to S13 and step S16 execute exactly the same processing as the processing of the same step shown in FIG. 7 described above, and thus detailed description thereof will be omitted here.

  In step 13, as described above, the error data 70 (FIG. 5) including the error information 41, the error recovery procedure 51, and the error recovery command 61 is generated, but the control unit 11 of the printer 210 generates the error data 70 here. The error data 70 is transmitted via the transmission / reception unit 14 to the PC 220 to which the image data has been previously sent (step S101). In the PC 220, when the error data 70 is received by the transmission / reception unit 25 (step S102), the error processing unit 90 processes the received error data 70, and information acquired from the error data 70 (error information 41, error recovery procedure). 51) and an error screen 80 (FIG. 6) including a recovery button 81 is displayed on the display unit 24 such as a monitor (step S103).

  Note that the error data 70 transmitted in step S101 can be in a general-purpose data format represented by a text format or a PDF (Portable Document Format) format. The destination of the error data 70 may be the PC 220 to which the image data has been sent, as illustrated here, or a device or printer selected based on information stored in the printer 210 in advance. A device selected based on information stored in the data received in 210 may be used.

  The user looks at the error screen 80 displayed on the display unit 24 of the PC 220 to determine whether or not to recover the error. If the user determines to recover, the user operates the mouse of the input unit 23, for example. A predetermined recovery operation such as clicking on the recovery button 81 is performed. Accordingly, the error processing unit 90 determines that the user performs error recovery (step S104, Yes), and transmits the error recovery command 61 included in the received error data to the printer 210 via the transmission / reception unit 25. (Step S105).

  When the error recovery command 61 transmitted from the PC 220 is received by the transmission / reception unit 14 (step S106), the control unit 11 of the printer 210 analyzes the error analysis command 61 and executes the error recovery command.

  For example, as illustrated in the error screen 80 of FIG. 6, the error that occurred is a paper size error with an error code 42 of E240 (FIG. 5), and the user displays the error screen 80 of FIG. When the recovery operation is executed using the recovery button 81 after confirmation, an error handling screen 82 shown in FIG. 6B is displayed on the display unit 24 of the PC 220 by executing the error recovery command. At this time, the control unit 11 of the printer 210 transmits the display data of the error treatment screen 82 to the PC 220 via the transmission / reception unit 14, and the error processing unit 90 transmits the display data via the transmission / reception unit 25 on the PC 220 side. The error handling screen 82 is displayed on the display unit 24.

  Further, the user selects and sets a regular paper size while checking on this screen to recover the paper size error. The paper size selected and set at this time is recognized by the error handling unit 90, and the transmission / reception unit of the PC 220 25 and the data transmission / reception unit 161 via the transmission / reception unit 14 of the printer 210.

  On the other hand, if the user has not executed error recovery, it is determined that the user does not perform error recovery (No in step S104), and the error recovery process is terminated without executing the error recovery command. In this case, if the user does not execute a predetermined recovery operation even after a predetermined time has elapsed after the error screen 80 is displayed and no error recovery command is sent from the PC 220 side, the user will receive an error. Judge that recovery will not be performed.

  In this embodiment, a printer that is an image forming apparatus is described as an example of an electronic apparatus. However, in addition to a printer, the present invention is applied to an electronic system that operates an apparatus from a host apparatus such as a scanner or a modem. Can be applied.

  Although not specifically described in the present embodiment, it is preferable to provide the storage unit 12 with an error recovery log storage unit that stores information about recovered errors. Thereby, it becomes possible for the user to confirm the recovered error later as in the first embodiment. Furthermore, by making it possible to identify the sender who sent the error recovery command, it is possible to easily collect information on the cause of the error.

  As described above, according to the system of this embodiment, when a simple error other than a physical error such as a paper jam occurs in the printer, the error recovery command and the command are executed on the PC connected to the network. When the printer is located away from the host model, in addition to reducing the labor and time spent on the work to recover the error and simplifying the work. Even so, you can easily recover errors.
